Online max-min fair allocation

Y Kawase, H Sumita - International Symposium on Algorithmic Game …, 2022 - Springer
We study an online version of the max-min fair allocation problem for indivisible items. In this
problem, items arrive one by one, and each item must be allocated irrevocably on arrival to …

Random assignment of indivisible goods under constraints

Y Kawase, H Sumita, Y Yokoi - arXiv preprint arXiv:2208.07666, 2022 - arxiv.org
We consider the problem of random assignment of indivisible goods, in which each agent
has an ordinal preference and a constraint. Our goal is to characterize the conditions under …

Leximin Approximation: From Single-Objective to Multi-Objective

E Hartman, A Hassidim, Y Aumann, E Segal-Halevi - ECAI 2023, 2023 - ebooks.iospress.nl
Leximin is a common approach to multi-objective optimization, frequently employed in fair
division applications. In leximin optimization, one first aims to maximize the smallest …

Contiguous Allocation of Indivisible Items on a Path

Y Kawase, B Roy, MA Sanpui - arXiv preprint arXiv:2401.04318, 2024 - arxiv.org
We study the problem of allocating indivisible items on a path among agents. The objective
is to find a fair and efficient allocation in which each agent's bundle forms a contiguous block …

Reducing Leximin Fairness to Utilitarian Optimization

E Hartman, Y Aumann, A Hassidim… - arXiv preprint arXiv …, 2024 - arxiv.org
Two prominent objectives in social choice are utilitarian-maximizing the sum of agents'
utilities, and leximin-maximizing the smallest agent's utility, then the second-smallest, etc …

Uniformly bounded regret in dynamic fair allocation

SR Balseiro, S Xia - arXiv preprint arXiv:2205.12447, 2022 - arxiv.org
We study a dynamic allocation problem in which $ T $ sequentially arriving divisible
resources are to be allocated to a number of agents with linear utilities. The marginal utilities …

Randomized Strategies for Robust Combinatorial Optimization with Approximate Separation

Y Kawase, H Sumita - Algorithmica, 2024 - Springer
In this paper, we study the following robust optimization problem. Given a set family
representing feasibility and candidate objective functions, we choose a feasible set, and …

Optimal design of lottery with cumulative prospect theory

S Akiyama, M Obara, Y Kawase - arXiv preprint arXiv:2209.00822, 2022 - arxiv.org
A lottery is a popular form of gambling between a seller and multiple buyers, and its
profitable design is of primary interest to the seller. Designing a lottery requires modeling the …
